2 Claims. (crea -1) My invention relates to improvements in paperradiator shields, and has for its primary object a radiator shieldformed from a single sheet of paper and having certain parts thereof cutaway so as to form flaps.

A further object is to construct a radiator shield from a single sheetof paper with certain parts cut away and which is provided with scorelines so that the same can be readily folded and then assenibled intoproper form.

A still fur her object is to construct a radiator shield folded from asingle sheet of paper in which the folds are so arranged that the samecan be readily made on a table thus obviating the necesl sity of havinga special form for the folding.

In the drawings:

Fig. l is a view of a sheet of paper illustrating the manner of cuttingand scoring the same.

Fig. 2 is a side elevation of a radiator in dotted ines showing myshield in position thereon.

Fig. 3 is a front elevation of the folded shield.

Fig. 5 is a horizontal section taken on the line 5--5 of Fig. 4.

Fig. 6 is a plan view of the shield after being assembled and folded.for shipping with parts broken away.

Fig. 7 is an enlarged fragmental section of one corner of the top of theshield taken on the line 'l--'7 of Fig.3.

Fig. 8 is a plan view of the shield when partially folded.

Fig. 9 is a fragmental view showing a still further development of thefolding; and

Fig. 10 is a plan view showing the-folding of one side of the shieldcompleted.

In the construction of my device I employ a sheet of paper 11. Thispaper is of such material or body as to be readily folded withoutbreaking the surface or rupturing the fibers but which is stiif enoughto retain its proper form after making. The sheet of paper issubstantially rectangular in form having edges 12 and 13 and ends 14 and15. Formed in the edges 12 and 13 and spaced some distance from the end14 is a cutaway portion l5 This portion is so cut as to leave atriangular projection 16.

Parallel to the ends 14 and 15 and at a pre determined distance belowthe cutaway portion 15 I form slots 17 and 18. The paper is then scoredas illustrated in Fig. 1 by dash lines so as to form folding lines 19,20, 21 and 22. These lines are parallel to the ends 14 and 15 andconsequently parallel to each other. Parallel to the edges 12 and 1-3are formed scorelines 23 and 24, respectively. p

Extending diagonally across the lower'portion of the sheet, that isbetween the score line 22 and the end 15, are score lines 25 and 25 Thescore lines, whichare parallel to the edges 14 and 15, form portions 26,27, 28, 29, and 30. The portion 26 when in assembled position projectsupwardly at an angle as in Fig. 4.

The portion 27 extends horizontally and the portion 28 extendsvertically, these three portions forming a dust trap. The portion 29forms the top ofthe radiator shield and the portion 30 the The portion31 between the score line 23 and edge 12 and the portion 32 between theedge 13 and score line 24 form the sides of the shield as illustrated inFig. 3.

It will he noted especially from Fig. 1 that the score lines 23 and24extend the full length of the material and that the cutaway portions15 and the slits 17 and 18 extend to these score lines so that portions33 and 34 will be formed integral with the top 29, these forming thesides of the top of the radiator shield.

In commencing to assemble the shield, the first step is to fold thepiston 30 along the score line 25. This will cause the same to assumethe position illustrated in Fig. 8. The portion 33 is then folded overon the portion 29 along the score line 23. The triangular projection 16is then folded outward along a diagonal line 35 so that it will assumethe position shown in Fig. 8. The portion 26 is then folded down overthe portion 27 along line 19 as illustrated in Fig. 8. Then theprojecting end 36 is folded down on a diagonal line 37 so that it willassume the position illustrated in Fig. 9. The fold along the line 20 isthen made and straightened out again after which the fold along the line21 is made. This causes the upper end of the shield to assume theposition illustrated in Fig. 10 after which the flap 16 is folded overon the line 21 sov that it will rest against the portion 28.

The flap 16 is then secured in position against this front flange 28 inany well known manner either by means of an adhesive or by means ofstaples. After this has been done, the shield is folded over on thediagonal line 25 and the operation on the other side of the device iscontinued in the same manner.

The device may be folded along the line 22 leaving it flat, and thepoint 38 caused by the diagonal folding is folded over so that the backend of the shield will be of the same width as the top thus making asmall rectangular package, which can be used for shipping and storagepurposes. It is understood, of course, that the device is completelysecured together after the folding and before being flattened out forshipping so that all the ultimate consumer has to do is to open up thedevice and it will be ready to be placed over a radiator.

Having 'fully described my invention, what I claim is: v p

1. The method of making paper radiator shields which consists in takinga rectangular sheet of paper and cutting away predetermined portions oneach side thereof and at a predetermined distance from itsupper edge soas to leave projectingtabs, forming a slit in each edge of said sheet ata predetermined distance below the cutaway p0r-' tions, forming aplurality of score marks across said sheet parallel to the upper edge ofthe sheet and to each other, forming a score line parallel to each sideof said sheet and spaced inwardly therefrom, then folding said sheetalong said score lines, and lastly folding over and securing said tabswhereby a radiator shield having a top pro-' vided on itssides and frontwith depending walls and a. dust trap, and an integral back memberprovided with forwardly projecting sides is formed.

2. The method of making paper radiator shields, which consists incutting away predetermined portions on each side of a rectangular sheetof paper and at a predetermined distance from its upper edge to therebyleave upwardly projecting triangular tabs and laterally projectingrectangular tabs immediately therebelow, forming a slit in each side ofsaid sheet at a predetermined distance below said tabs and inwardly adistance equal to the projecting length of the rectangular tabs, foldingsaid sheet parallel to its'upper edge along a plurality of parallellines, then folding each of the sides of said sheet along alongitudinally extending line, folding over and securing said tabs, andfolding the lower portion of the sheet so as to shorten the same,whereby a radiator shield having a top provided onits sides and frontwith depending walls and a dust trap and an integral back memberprovided with forwardly projecting sides is formed.
